Title: Manufacture of multilayer printed wiring board
Inventor: HARA TAKASHI
IPC: H05K3/46
Filed: 1990-10-19
Abstract: PURPOSE:To enable a connection point where a via and a conductive layer are connected together to be easily confirmed through an artwork or the like even if the via is small in diameter by a method wherein a step in which a conductor layer provided with a mark formed on its part connected through the via is made to adhere to an insulator layer is provided. CONSTITUTION:First of all, an artwork operation is carried out basing on design data, and the pattern of a conductor layer which is pasted on an insulator layer is formed into a film. A mark is formed on the film concerned. In succession, the conductor layer is formed on the insulating layer using the film. The insulator layers on which the conductor layer is pasted are laminated, and through-holes are bored in the laminate concerned by a drill or the like. At this point, the mark formed on the conductor layer is eliminated through boring. Thereafter, the through-hole is plated to electrically connect the conductor layers for the formation of a via. Finally, solder resist is applied to form a multilayered printed wiring board. As mentioned above, a mark is provided to a part of a conductor layer which is connected to a via at an artwork stage, so that the part concerned can be easily and visually confirmed.

Title: Ultrasonic actuator
Inventor: TSUBATA TOSHIHARU
IPC: H01L41/09
Filed: 1992-09-24
Abstract: PURPOSE:To improve a driving force and the speed of an actuator by providing a driven member brought into contact with a slide of a vibrator so as to be pressed by a predetermined pressure and to be relatively moved. CONSTITUTION:An ultrasonic actuator is applied by preload by clamping a screw 6 through two laminated piezoelectric elements 4a, 4b by an elastic element 2 having a protrusion for fixing the elements 4a, 4b at a side face to a base 1, and an entire vibrator is bent to be vibrated when alternating voltages are so applied to the elements 4a, 4b that phases of elongation and contraction of the elements 4a, 4b become reverse to one another. When the alternating voltage is applied to a laminated piezoelectric element 3 to be elongated and contracted to be vibrated, the vibrator is longitudinally vibrated. When the phases of the voltages to be applied to the element 3 are so regulated that the phases of the bending vibration and the longitudinal vibration are deviated by 90 degrees, an elliptical motion is generated at a slide 5 at an end of the vibration so that a driven member 7 is brought into frictional contact with the slide 5, and the vibration and the driven member are relatively moved. As a result, the actuator having a large driving force and an improved speed is obtained.

Abstract: PURPOSE:To contrive the improvement of the high-speed operation of a device without reducing a current gain as well as to make it possible to enhance sufficiently a collector-base withstand voltage by a method wherein a base region is doped slantingly. CONSTITUTION:An i-type Al0.3Ga0.7As emitter region 2 is formed of an I-type semiconductor material having a wide band gap adjoining an n-type GaAs emitter region 1 having a constant donor concentration. An n-type GaAs base region 3 has a high donor concentration on the side near the emitter barrier. The donor concentration is lower in a position nearer the collector barrier region 4 and farther the emitter barrier. Thereby, the high-speed operation of the device can be improved without lowering the current gain and collector- base withstand voltage. Moreover, as the potential barrier phic of the region 4 is sufficiently high in a state that a current is not made to flow, a leakage current is small and a sufficient withstand voltage VCB between a base and collector is secured.

Next, a signal from an operating part (not shown in figure) written in a buffer 35 via a signal monitoring part 34 is investigated, and it is investigated whether the operating part is placed under a key input operation. At this time, when a key input such as the registration of a telephone number, etc., is executed, indication to output a recording paper absence command is issued to a recording paper control part 33. When the recording paper absence command is outputted, an incoming call from the line is neglected even when the incoming call is received from a GIV line.

Abstract: PURPOSE:To connect a slotting capacitor and a transistor with a single crystal region as well as to isolate elements at the same time by a method wherein a TFT forming Si single crystal is grown on an SiO layer using a substrate Si single crystal as a seed. CONSTITUTION:An Si single crystal layer 3 is grown on an SiO2 layer 2 using the single crystal to a P-type Si substrate 1 as a seed, and the film 4 consisting of an SiO2 film, an Si3N4 film and an SiO2 film is formed thereon. Then, a photoresist is applied to the film 4, and a patterning is performed on the photoresist by performing a photoetching starting at the edge of the SiO2 layer 2 on the place shifted by 0.3mum, for example, of a window of 1mum in width, for example. Subsequently, the film 4 and the layer 3 are left a little, and the other part of them is removed. Then, when a groove is cut after the surface of the formed groove has been oxidized, a groove of 0.7mum in width is formed. An N<+> region 5 is formed by diffusing donor impurities from the inner surface of the groove. After the upper film of the film 4 and the SiO2 film have been removed, the surface of a polycrystalline Si 7 is oxidized, the Si3N4 film of the film 4 is removed, and a transistor is formed by growing the gate oxide film of the transistor.
